DEVELOPMENT OF METHODOLOGY FOR THE ANALYSIS OF WATER QUALITY IN RIVERS

Abstract

The Bermejo River, located in the San Pedro Sula region of Honduras, is a vital resource for the city and its economy, playing a crucial role in commercial activities and meeting basic needs, particularly in communities lacking proper access to water infrastructure. Despite its significance, there is a notable lack of information regarding the water quality in this river. This research aims to develop a detailed method that serves as a guide for future water quality analyses in rivers including Bermejo. The necessary procedures for sample collection are outlined, along with strategically selected sampling points. Parameters to be assessed include the presence of detergents and chlorine, indicators of fecal contamination, chemical oxygen demand, dissolved oxygen concentration, presence of fats and oils, pH levels, and fecal coliforms. The designated sampling points for this study are point a, located at coordinates 15°31'56.6"N 88°00'51.8"W, and point b, at 15°30'46.2"N 87°59'33.5"W. Once data is collected and results of tests for each parameter are analyzed, the Canadian council of ministers of the environment water quality index (CCME WQI) is applied. The results yielded a score of 29.51, indicating that the water quality falls into the lowest category, considered poor. This study provides a systematic initial insight into the water quality of the Bermejo River and establishes the groundwork for future research and monitoring. The findings underscore the need for interventions and policies addressing pollution sources and promoting improvements in the water quality of this crucial resource for the community.
